Expert Answer
(a) Insoluble salts are prepared by precipitation.
(b) (i) Sodium hydroxide when added to zinc nitrate, a white precipitate of zinc hydroxide is formed which is soluble in excess of NaOH. On adding sodium hydroxide solution to calcium nitrate a white precipitate of Ca (OH)2 is formed which is sparingly soluble.
(ii) Sodium hydroxide when added to Iron (II) chloride forms a dirty green ppt. of Fe(OH)2 whereas Iron(III) chloride forms a reddish brown ppt. with NaOH.
